Timeline for Snape's change of heart (was: Snape, Voldemort, and teaching)

>> Two thoughts here. First, re: Mooseming's potential timeline.
Could it be possible that Snape was *still* on the side of Voldy at
the time he started working at Hogwarts? Perhaps he was pretending
to have joined DD's side but was still loyal to Voldy? And then, he
**did** get access to that list of births and, when he did,
discovered James and Lily's son was on the list? And *this*
knowledge then caused him to switch sides for real? <<

HunterGreen (hello SSSusan):
The text appears to support that timeline, at least in the Spinner's 
End (it was a possibility I mentioned upthread). However, if it did 
work out that way, it would have been rather hard for Dumbledore to 
trust him, don't you think? First he *pretends* to repent his ways, 
then he *really* repents them and goes to Dumbledore explaining that 
the first time he was faking....wouldn't that seem a little off to 
Dumbledore? I suppose if he was admitting to telling Voldemort that 
the Potters were now a *direct* target, then it might make Dumbledore 
trust him a little more, but if he had believed him the first time, 
during the time Snape admits (for the sake of this timeline) he was 
faking, how would he ever believe him again?

This timeline continues to confuse me, unless I look at it from the 
point-of-view that Snape never switched sides at all. Because if he 
didn't, we know why Dumbledore would think that he did (because Snape 
did, on Voldemort's orders, go to him and pretent to repent his 
ways). If he was faking, and always faking, then it makes sense. 
Otherwise, I can't seem to work it out (unless Snape and Dumbledore 
somehow gave Voldemort the idea of sending Snape to Hogwarts....which 
just seems unlikely).
